SIMON DRUM, OF ALLEGHENY CITY, PENNSYLVANIA.

IMPROVEMENT IN SHUTTER-HINGES.

Specification forming part of Letters Patent No. 48,264, dated June 20, 1865.

To allwhom it may concern: Be it known that I, SIMON DRUM, of the city andcounty of Allegheny, and State of Pennsylva'nia, haveinvented a new and useful Improvement in Hinges and I do hereby declare that the following is a full and exact description for Window Shutters;

thereof, reference being had to the accompanyingdrawings,and to the letters of reference marked thereon.

The nature of my invention consists in. cutting away a portion of the metal which surrounds the pintle of the male part of the hinge for the purpose of forming an inclined plane on the right and left hand side of the pintle, and a horizontal plane on the back and front side of it; also, in cutting away a portion of each end of the knuckle of the female part of the hinge, so as to form inclined and horizontal planes which will in size and form correspond to the inclined and horizontal planes on each of the sides of the pintle, said planes being so arranged that the hinge will in swinging the shutter out from its place in the window-frame cause it to move on a line with the plane of the upper side of the window-sill until it has cleared the sill, and then to gradually sink until the faces of the planes come together, in which position the window-shutter will be held back against the wall of the'building.

My invention also consistsin making by the use of and. by my peculiar arrangement of the planes herein described a hinge which will answer for either the right-hand or left-hand side of the shutter and window-frame.

i To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, Figure 1 is a perspective view of the male part of the hinge. Fig. 2 is a perspective view of the female part of the hinge. Fig. 3 is a side view of the hinge, and represents the relative position of the two parts when the shutter is closed. Fig. 4 is a side view of the hinge, and represents the relative position of the two parts when the shutter is open and pressed back against the wall.

In the drawingsflt represents the part of the hinge which is secured to the window-frame. F represents the part which is secured to the shutter. S represents screw-holes, which may be countersunk on one or both sides of the hinge. D represents the metal which surrounds the pintle. P represents the pintle, which may be made movable or secured permanently in its place. K representsthe inclined planes on the right and left hand sides of the pintle. m and m represent the horizontal planes on the back and front sidesof the pintle P. B represents the knuckle of the female part of the hinge. X represents the opening through the-knuckle for the pintle. Y represents the inclined planes on each end of the knuckle, and 'n and n represent horizontal planes.

It will be observed that by making the inclined and horizontal planes on each end of the knuckle B that the hinge will answer equally well for either the right or left hand side of the shutter; and it will also be observed that my improved hinge can be made of either cast or wrought iron, and that it can be made in the form of strap or butt hinge.

The operation of my improved hinge is as follows: In opening the shutter the plane a moves on the plane m until the shutter has swung clear of the window-sill, then one of the inclined planes Y travels down one of the in clined planesKuntil all thefaces of the planes come together, as represented in Fig. 4 of the drawings, in which position the shutter is held back against the wall of the building by the action of the inclined planes and the weight of the shutters. In closing the shutter one of the inclined planes Y travels up on one of the inclined planes K until the horizontal plane 11/ comes on the plane m, which will allow the under side or end of the shutter to swing to on a line with the plane of the upper side of the window-sill.

The advantages of my improvement areas follows: Myimproved self-fasteninghinge will answer for either the right or left hand side of the shutter, which overcomes the necessity of keep in g them in pairsto Wit, right andleft handed hinges-which is always a source of inconvenience, annoyance, and trouble to the manufacturer, dealer, and consumer or user. Themanufacturer in making right and left self-fastening hinges is required to watch with care over his stock of hinges, or otherwise he will have on hand more of one kind than desired-that is to say, more right than left or more left than right handed hinges. The dealer often finds Now, by my ,the female scribed.

self-fastening hinges trouble in kee ping his stock of self-fastening hinges unifor m, for sometimes he sells more right-handed than left handed hinges, and vice versa. The consumer finds that by the use of right and left handed self-fastening hinges he is subjected to expense and annoyance, for when a hinge is broke or part of one is lost he must purchase a pair, when, perhaps, he only wants part of a single hinge, and must note with care what side of the shutter the broken or lost part of the hinge belongs to.

improx'ement, all of this inconannoyance, and trouble is overcome making both ends of the knuckle of part of the hinge to correspond to the planes around the pintle, as herein devenience, simply by Another advantage obtain provement consists in avoidin and recesses common to self- In my hinge there are no pr olf and no recesses to fill up with dust, rust, paint, snow, or ice. The objection to the use of hinges having projections and recesses are overcome by my improved mode of making which is simply to cut' ed by my imgthe projections fastening hinges. ojections to break away a portion of each end of the knuckle of the female part of the hi metal which surrounds t part of the bin in described.

A further advanta nge and apart of the he pintle of the male ge, so as to form the planes hereters Patent, is

Making on each end of the knuckle of the female part of the hinge two or more planes corresponding to two or more planes around the pintle of the male part of the hinge, substantially as herein described, and for the purpose set forth.

SIMON DRUM.
